We are considering use of multiple FPGA using PCI express slot.
We will control the Multi FPGA PCI-E controlled by one host PC. (FPGA board is VCU-108)
Now, our test is well done between one host PC and one FPGA with PCI-express interface.
The problem is that when we try to use two FPGA board and put the two PCI-express to the PCI-expansion, our host PC cannot boot properly (shows the bios booting error)
We already tested the PCI-expansion test (one GPU, one FPGA works fine.)
We are using AXI bridge for PCI-express IP.
Can you share the example if user want to connect multiple FPGA via PCI-E I/F?
PS. if you want to specific detail. we can share the environment. let us know support email.

Do you mean that you want to insert 2 PCIE card into 2 slots and to work with one host ?
please check if you have used the same device ID for the two board.
please also check if the link up is asserted , this will help to know if it's a SW related or HW related issue
